Lake County reports about 12 new HIV diagnoses per 100,000 residents, near the US average. Whether you have symptoms or just want peace of mind, you'll find local clinics and at-home kits for STI testing in Upper Lake, California. Some clinics take walk-ins for same-day testing, while labs and at-home kits let you plan around your own time — see your options below.
Available testing centers
7 testing options are listed for Upper Lake, CA. The nearest, Sutter Bay Hospitals, is about 4.0 miles away. Compare community and public clinics, private labs, and at-home kits below.
Listings tagged Community health center are federally funded health centers and rural clinics that treat everyone regardless of insurance or ability to pay: required to bill on a sliding fee scale and provide confidential care, and in many states minors may consent to their own STI testing. A Title X tag flags centers funded for confidential family-planning services; confirm current participation when you call.

A community safety-net rural health clinic about 4 miles from Upper Lake. Sliding-scale STD testing and care are typical here, call ahead to confirm the exact panel and pricing.
Tests offered
Mendocino Community Health Clinic in Lakeport runs on a sliding scale with Medicaid, Medicare, and private insurance accepted, covering HIV, syphilis, gonorrhea, chlamydia, hepatitis A, B, and C, and TB: with same-visit treatment for bacterial infections, HPV vaccine, and care delivered in Spanish.
Without Spanish at the clinical level, a diagnosis lands incomplete. Instructions misread, follow-up missed, medication taken wrong. At Mendocino Community Health Clinic, Spanish isn't routed through a separate step; the care itself happens in Spanish, keeping treatment on track from first test to last dose.
Mendocino Community Health Clinic prescribes both PrEP and PEP directly, which means a patient establishes prevention care with the same provider handling their STI testing: no separate specialist, no gap between the conversation and the prescription.
For someone managing substance use without a stable care relationship, Mendocino Community Health Clinic holds both treatment tracks (substance-use care and STI testing, counseling, and treatment) so the two conditions are addressed by the same clinic rather than pulled apart across separate systems.

STD stats & rates
How reported STI rates in Lake County, the county that includes Upper Lake, compare with California and U.S. averages, based on the most recent 2023 surveillance data. An estimated ~16% of residents are aged 15–34 (ACS), the age group with the highest reported chlamydia and gonorrhea rates nationally.
#28 of 58 California counties for chlamydia, a higher rate than 52% of the state
| Infection | Lake County | California | United States |
|---|---|---|---|
| Chlamydia | 340.3 231 cases ▼ 31% | 491.1 | 492.2 |
| Gonorrhea | 123.8 84 cases ▼ 35% | 190.2 | 179.5 |
| Syphilis (P&S) | 19.2 13 cases ▲ 18% | 16.3 | 15.8 |
| Syphilis (early) | 4.4 3 cases ▼ 77% | 19.1 | 16 |
| Syphilis (late/unknown) | 36.8 25 cases ▼ 21% | 46.7 | 29.5 |

Reading these numbers: reported case rates only count infections that were actually tested for and diagnosed, so they track local screening effort as much as true spread: a higher rate can reflect more testing, a lower one less. Either way, most STIs cause no symptoms, so treat the figures above as context rather than a verdict, and test on the CDC's schedule regardless of how your area looks.
Between 2020 and 2023 in Lake County, chlamydia has fallen from 359.4 to 340.3 per 100,000 (5%), gonorrhea has fallen from 164.3 to 123.8 per 100,000 (25%), and P&S syphilis has fallen from 36.7 to 19.2 per 100,000 (48%).

Community health context
Sources: CDC PLACES (ZIP), County Health Rankings, CDC/ATSDR SVI, HRSA HPSA, HRSA MUA/P, Neighborhood Atlas ADI. Lower insurance coverage, fewer routine checkups, and a thin primary-care ratio all raise the value of low-cost public clinics and at-home testing in Lake County.
Local HIV snapshot
Lake County HIV care continuum (2023)
Lake County recorded 12.2 new HIV diagnoses per 100,000 (2023), against 14.9 statewide and 13.7 nationally. Among Lake County residents living with HIV, 87.7% are in care · 81.2% are virally suppressed. Early, routine testing is what moves these numbers: it is the entry point to PrEP, treatment, and viral suppression.
Sources: AIDSVu (Emory/Gilead) · CDC AHEAD · CDC AtlasPlus · CDC NCHHSTP AtlasPlus (county care continuum). The CDC recommends everyone aged 13–64 test for HIV at least once: every lab and clinic listed above offers HIV testing, and free rapid HIV testing is available at a local health department.
Congenital syphilis, passed from parent to baby in pregnancy, is the fastest-rising STI in the country. U.S. cases climbed from 2,163 in 2020 to 3,882 in 2023. It is almost entirely preventable: the CDC recommends a syphilis test at the first prenatal visit, and every clinic and lab listed for Lake County tests for syphilis.

Two things that actually depend on California law: who can consent, and whether partners can be treated without their own visit. Everything else about testing privately is the same nationwide (see below).
In California, a minor aged 12 or older can consent to confidential STI testing and treatment on their own, no parental permission is required.
California permits Expedited Partner Therapy (EPT): if you test positive for chlamydia or gonorrhea, your provider can give you medication (or a prescription) to pass to your partner, no separate exam or appointment needed for them.
Keeping a test private works the same in every state. Whether an STD test shows on insurance (the EOB), how to test anonymously, and self-pay options that leave no insurance trail don’t change by location.
